Description: A clear quartz crystal with lovely growth patterns and termination facets. The bottom has re-crystallized, and a minute (6½ mm long) crystal is attached near the centre of it.
Inside the crystal are a few minute balls of olive-green chlorite (not easily visible with the naked eye, strong magnification needed - see example). On the surface are several round indentations, some partially filled with goethite. These were probably caused by the chlorite balls that were initially on the outside, and only partially embedded in it, but have since eroded away, prior to the specimen being mined.
The specimen has a minute nick to its termination point. The lower end, which is slightly milky, has a flaw across. There is also a natural pressure mark, and bits of iron oxide attached to the specimen.
